Method Details

getElementType

public final Class getElementType()

Returns the element type of this list property.

For example, for a node type like CompilationUnit, the "imports" property returns ImportDeclaration.class.

Returns:

the element type of the property

cycleRisk

public final boolean cycleRisk()

Returns whether this property is vulnerable to cycles.

A property is vulnerable to cycles if a node of the owning type (that is, the type that owns this property) could legally appear in the AST subtree below this property. For example, the body property of a MethodDeclaration node admits a body which might include statement that embeds another MethodDeclaration node. On the other hand, the name property of a MethodDeclaration node admits only names, and thereby excludes another MethodDeclaration node.

Returns:

true if cycles are possible, and false if cycles are impossible
